PDP's evidence-based and continual improvement research ensures the highest degree of accuracy and predictability, bar none.
Since the beginning, stringent research standards have been used so all PDP system results are as accurate as they can be.
These standards ensure a comprehensive, predictable and accurate assessment system to place employees, help team members work together, and empower managers. The result is a top notch solution of helping businesses understand their people and be more successful.
Committed to Continuous Improvement
Data were analyzed using the Rasch measurement model, which is a special case of Item Response Theory and provides a contemporary approach to assess reliability and validity.
As part of the continual process of investing in the evolution and quality of the ProScan, the instrument was evaluated for response integrity and quality control based on 50 criteria. Performing these rigorous evaluations helps ensure that ProScan remains a trusted and reliable source for trait assessment.
A long-term study was conducted to test the psychometric properties of the ProScan Survey, including the testing of new words due to language evolution and change over time, to determine if even greater accuracy could be achieved.

ProScan Survey Development and Psychometric Assessment. Assessing psychometric properties at various time points throughout the years during its utilization.
The ProScan Survey was developed from a sound theoretical base, a carefully selected normative sample, and appropriate statistical procedures. Monograph No. 10 describes work performed on the standardization of the ProScan Survey. Evidence from initial experiments showed high coefficients of reliability and validity.
The Post Normative Study was designed to document certain practical effects of the structural integrity of the ProScan Survey. The plan called for analyses of responses to the ProScan Survey obtained on two groups of adults who were thought to differ significantly on one or more behavioral traits. This was a deliberate attempt to stretch the instrument, to determine if the set of terms that predict a given behavioral trait is the same when the group means are at opposite ends of the scale.
A series of analyses were performed to investigate the predictive validity and disparate impact of the PDP ProScan and JobScan.
